That is an excellent question, Alistair. The iris analysis is based on scientific research that has been done for many years by professionals in Europe and The States. The iris is actually mapped as to what regions in the iris correspond with what organs in the body, but the key to understanding iridology is understanding the anatomy of the eye and its relationship to the central nervous system. In other words, an iridologist has very clear and specific anatomical features he or she will look for to provide an assessment. I would encourage you to visit the website of the IIPA (International Iridology Practitioners Association). It will give you a look at what Iridologists are working on at the present time.
